No two phase. Fun to argue though because 'phase' has two different meanings that apply. Wiki explains it better than I can.
There are two phases or a split phase for those that like to parse words and need to refer to wiki
i.e. each line is 180 degrees out of phase (an angle):
Vphase1 = Vrms x sin (A)
Vphase2 = Vrms x sin (A+180)
Vphase3 = Vphase1 - Vphase2 (any phase other than 180 degrees results in less than 240V RMS)
A three phase system has three phases, each 120 degrees out-of-phase with each phase.
And for those that must always refer to wiki; https://en.wikipedia.org/wiki/Phase_(waves)
In physics and mathematics, the phase of a periodic function F of some real variable t is the relative value of that variable within the span of each full period.
Should we continue parsing terms?
